Configure System Maintenance Properties

This topic describes how to configure Publisher server properties.

Set Server Caching Specifications

When Publisher processes a report, the data and the report document are stored in cache.

Report-specific caching of data sets can be set as a report property.

To configure caching at the server level:

  1. In the Server Configuration page, set the following properties:
    • Cache Expiration — Enter the expiration period for the cache in minutes. The default is 30.
    • Cache Size Limit — Enter the maximum number of cached items to maintain regardless of the size of these items. The default is 1000.
    • Maximum Cached Report Definitions — Enter the maximum number of report definitions to maintain in cache. The default is 50.
  2. To manually purge this cache, on the Manage Cache tab, click Clear Object Cache .

Set Retry Properties for Database Failover

If Publisher fails to connect to a data source through the defined JDBC or JNDI connection, Publisher switches to the backup database.

The following properties control the number of retries that are attempted before switching to the backup connection for the database.

  • Number of Retries

    Default value is 6. Enter the number of times to attempt to make a connection before switching to the backup database.

  • Retry Interval (seconds)

    Default value is 10 seconds. Enter the number of seconds to wait before retrying the connection.

Set Report Viewer Properties

The Report Viewer Configuration tab enables you to set the Show Apply Button report viewer property.

If Show Apply Button is set to True, reports with parameter options display the Apply button in the report viewer. If you change the parameter values, click Apply to render the report with the new values.

If Show Apply Button is set to False, the report viewer does not display the Apply button. If you enter a new parameter value, Publisher automatically renders the report after the new value is selected or entered.

You set this property at the report level to override the system setting.

Clear Report Objects from the Server Cache

Use the Manage Cache page to clear the server cache.

The server cache stores report definitions, report data, and report output documents. If you need to manually purge this cache (for example, after patching) use the Manage Cache page.

To clear the report objects from the server cache:

  1. From the Administration page, select Manage Cache.
  2. On the Manage Cache page, click Clear Object Cache.

Clear the Subject Area Metadata Cache

You can clear the subject area metadata cache.

BI subject area metadata such as the dimension and measure names are cached at the server to quickly open the report in report designer. You can manually clear this cache if the BI subject area is updated through a binary repository (.RPD) file.

To clear the subject area metadata cache:

  1. From the Administration page, select Manage Cache.
  2. On the Manage Cache page, in the Clearing Subject Area Metadata Cache section, click Clear Metadata Cache.

Purge Job Diagnostic Logs

You can purge old diagnostic logs to increase the available space on your system.

The retention period of job diagnostic logs is set to 30 days, by default. If you frequently enable diagnostic logs, these diagnostic logs might consume space in the database, and you might need to periodically free the space consumed by the old diagnostic logs. You can manually purge the job diagnostic logs older than the retention period .

To purge the job diagnostic logs:
  1. On the Administration page, under System Maintenance, select Manage Job Diagnostics Log.
  2. Click Purge log beyond retention period.

Purge Job History

Use the Manage Job Diagnostics Log page to purge old job history.

The retention period of a job history is set to 180 days, by default. You can manually purge the history of jobs that are older than the retention period. When you purge old job history, the saved output, saved XML, job delivery info, and the job status details of the old jobs are deleted.

To purge old job history:
  1. On the Administration page, under System Maintenance, select Manage Job Diagnostics Log.
  2. Click Purge scheduler metadata.

Upload and Manage Configuration-Specific Files

Use Upload Center to upload and manage the configuration-specific files for font, digital signature, ICC profile, SSH private key, SSL certificate, and JDBC client certificate.

To upload and manage the configuration-specific files:
  1. On the Administration page, under System Maintenance, select Upload Center.
  2. Click Browse and select the file you want to upload.
  3. Select the configuration file type.
  4. If you want to overwrite an existing file with the new file, select Overwrite.
  5. Click Upload.
  6. To manage the uploaded files, use the Filter By Type field to filter the files in the table.
